Question

我正在开发一个RESTfull API，它可以从firebase数据库中获取数据我成功地检索了与此相同的数据

{
"Admin": {
    "-L-ck6q9elghYywXHneg": {
        "accepted": false,
        "date": "7/12/2017",
        "hour": "4:32",
        "numberOfPeople": "3",
        "tableInfo": ""
    }
},
"Guest": {
    "-KvJja_r0beLtdoRc29f": {
        "accepted": true,
        "date": "1/10/2017",
        "hour": "0:43",
        "numberOfPeople": "",
        "tableInfo": ""
    }
}

}

现在，我想访问＆＃34;接受＆＃34;两个记录中的字段，而不知道密钥是什么＆＃34; Admin＆＃34;或＆＃34;访客＆＃34;怎么可以这样做？

我试过这个

foreach ($users as $user) {
        $data[$counter]['accepted'] = $user->accepted;
        $counter++;
    }

但是没有成功

Answer 1

这是一个像这样的对象

foreach ($users as $key=>$user) { //changed this line
    $data[$counter]['accepted'] = $user->accepted;
    $counter++;
}

Answer 2

尝试 $ user [0] - ＆gt;接受

foreach ($users as $user) {
    $data[$counter]['accepted'] = $user[0]->accepted;
    $counter++;
}

Answer 3

刚刚测试过，与您的数据完美配合：

$users = json_decode($users, true);
foreach ($users as $user) {
   $data[$counter]['accepted'] = array_first($user)['accepted'];
   $counter++;
}
